We opened BGB CrossFit in 2014 because we wanted to provide the Fayette County Community with a Premier Health and Fitness experience. Each of us was drawn to CrossFit for a different reason, but we found the concept of training and the methodology to be universally applicable to all ages and demographics. It is our mission to help each client who walks through our doors achieve Optimal Health and improve their Fitness to levels they didn’t think were possible for them.

Through continued education and listening to the needs of our clients, we expanded our offerings outside of just training services to include functional nutrition, functional movement screening, and Massage Therapy Services. These additional services are what set us apart from other gyms in our area and what makes BGB CrossFit the premier holistic health and wellness facility for Fayette County.
